Home Depot Online Unreliable

On Nov. 26, 2007 HomeDepot.com featured an American Standard Cadenza Elite Corner Whirlpool Model 6060E.020 for a sale price of $599 with free shipping. I ordered one, gave my credit card and received a 'Thank You For Your Order' confirmation and order number. Three days later I received an email that they have cancelled the order. When I called a manager told me they are now out of stock but I could reorder - but at the regular price - even though I offered to wait for delivery or even accept a slightly different model or color or make. It appears they just want to get out of honoring a highly featured sale price. No wonder the Co's stock is doing so poorly with such lack of customer service or integrity. Their order acceptance means nothing.
